I see, thanks a lot for your answer ! But assuming I want to keep similar performance in most games, I'd need to overclock the i9-9900KF to a similar clockrate : wouldn't I then need a new cooler ? I'm pretty sure the VRMs on my mobo aren't the best either, so I'm unsure how I'd manage to reach 4.7-8 GHz safely. (if I were to change my motherboard I'd rather use that occasion to get something even more recent like a 10700KF or 5800X, but that's another topic)

I'm very surprised about 450W being enough for an oc'd 9900KF + 1070 but if you say so I guess I'm overestimating how much it puts out.

I definitely don't need more than 8/16 of course, I'm no professional.

5.0 single core boost, 4.7 all core seems good enough to me. The cooler is good enough that it shouldn't overheat on stock clocks (especially if you undervolt it a bit) and I doubt the VRMs will burst into flames at stock either. Wouldn't expect much of an OC, but it's faster than what you've currently got at stock speeds so I don't see that being an issue.
You don't have to go all out and get a 9900K(F) either, that's just the fastest (and most expensive) CPU you can get without replacing the mobo.

Depends on the 1070. Reference design/FE is 150W, aftermarket goes up to 250W in theory, but most are 180W, with peaks to 190-200W.
Yes, overclocked you can push the 9900K to 250W on a dedicated CPU stresstest like Prime95 and that's awfully tight with your PSU (though barely doable), but actual, real-world all core loads at stock? 120-150W, plenty of headroom there. Light OC like permanent 4.7 all core instead of only boost for x seconds is fine.

All this sounds a bit tight, but it might be worth it, thanks for the advice !

Now let's assume that in a different scenario I were to gift/sell mobo+CPU+cooler instead of just the chip (a few people asked me for either of those), what new "combo" should I then go for ? I could gift/sell the PSU as well if necessary, or gift/sell/keep a small secondary PC with all those 4 components + a few second-hand ones like I intended to in my first post.

Budget for the upgrade should be around the same, that is 600-700 euros max.

It's a 450W PSU and it isn't trash so you can actually draw 450W. There's no need for a 100W buffer. It's supposed to be within spec at 100% load and will be completely fine with spikes to 110% since spikes from the sustained load are expected. Non-oc with a FE 1070 you'd be at <350W under full load, "normal" aftermarket 1070 (~180W) + lightly oc'd 9900K would be around 400W for the whole system. Even with some spikes that's well within the PSU's capabilities.

You'd need RAM for the secondary PC or buy new one for your primary, obviously.
10700K would be within budget, but it would be very weird since the ridiculous prices for Z490 mobos mean a 9900KF (same speed) + a cheap quad core including mobo might actually be cheaper, let alone just a cheap-ish used mobo for the 8350K.
5800X is expensive enough that I don't think a cooler and mobo good enough for a decent overclock would leave enough for an SSD without maxing out the budget completely.
5600X would be a tradeoff, slightly slower in multithreaded than a 9900K, but faster singlethreaded, though obviously more expensive since you need a new mobo and cooler.
3700X would be definitely weird, if you can even find one for a reasonable price. Multithreaded about the same as the 5600X, maybe slightly better, but at best the same singlethreaded as the 8350K you already got.

Alright thanks for the input, so I would say we have 2 scenarios then, depending on whether I sell or gift the CPU+mobo+cooler combo or not :

  • if I don't, I should probably go for the 9900KF, keep the PSU, mobo and cooler, aim for a 4.7 GHz oc (will the cooler suffice for that too ? Else I can keep it for the 8350K and buy a beefier one) or keep it stock and rely on boosts, and then figure out a potential 8GB RAM + cheap used mobo for the 8350K, plus (used) case/GPU/PSU/small SSD for cheap, and get an NVMe M.2 500GB SSD for the main PC ; how much would that possibly amount to ? do you have any mobos, coolers and NVMe's to recommend (if you have time for this of course) ?
  • if I do, then I would probably say, based on the information you gave me, that either the 10700K or the 5600X are the best options and that they're fairly equivalent? In which case I would only need a mobo and a cooler for either of those, along with an NVMe M.2 SSD (and maybe a PSU I suppose unless it's a similar power draw to the 9900KF ?), but nothing else because of no secondary PC. Would you have any recommendations in that case too ?

Thanks again for all the advice !

Like I said 4.7 is the stock boost clock so your current cooler should be able to handle that, probably slightly more.
There's always delidding...

The MSI Z370 A-PRO is as bad as it gets for Z370, so any Z370/Z390 you can get will be at least as good. It might even be worth to use the "new" used mobo for the 9900KF instead. Yes, if you can find an Intel fanboy who is upgrading to a 10900K and selling a 9900K(F) that wasn't overclocked insanely high + mobo it might be an even better deal.
Remember that a 9900K(F) is simply the best you can get that would fit your mobo, but a 9700K or 9600K would still be an upgrade by 100/50% in multithreaded.
For SSDs https://www.anandtech.com/show/9799/best-ssds or other guides.
You should be able to find entry level 500GB NVMe SSDs around 50-60€ and mainstream starting at around 65€.
For the 8350K any 120mm or more single tower cooler should be more than enough.

10700K vs 5600X is a slight tradeoff on multithreaded vs singlethreaded. There's only so much 6 cores can do if that program doesn't show vastly better SMT scaling on AMD.
Z490 mobos are slightly more expensive and don't have PCIe 4.0 though.
10700K is basically a 9900K, very similar power draw, 5600X would be less.

EDIT: Just so we're clear: I didn't forget about mobo recommendations, I just didn't feel like doing a whole bunch of them for different levels of overclocks, depending on how much are willing or able to afford depending on how much you're spending on the SSD and RAM and other stuff for the second pc and doing it twice for both 10700K and 5600X.
You're smart and motivated enough to make a decision on those on your own, which will give me a much clearer budget and narrower restrictions to work with, drastically reducing the time and effort needed.
tl;dr

Thanks a lot for the advice, no worries for the being lazy part I can perfectly understand !

I'll wait until I'm sure whether I'm selling/giving the CPU+mobo+cooler combo or not and what CPU I'd like to get depending on that first condition as you suggested, and then ask again for further advice on mobos, coolers, PSUs and SSDs.
